· Kupukuta kwa makina ndi njira yochokera pamwamba kupita pansi, yooneka ngati thupi. Kumapaka, kudula, ndi kuwononga pamwamba kuti pakhale pathyathyathya. Ndikwabwino kwambiri pakupeza Ra yotsika kwambiri (yofanana ndi galasi) koma kumatha kusiya zodetsa zomwe zili mkati, kapangidwe kake kamene kamasintha, komanso kupsinjika kotsalira.
· Kupukuta ndi electrochemical ndi njira yochokera pansi kupita mmwamba. Kumasungunula mosankha nsonga za kuuma kwa pamwamba, kulinganiza micro-profile ndikuchotsa wosanjikiza woonda wa zinthu. Nthawi zambiri kumabweretsa Ra yapamwamba kuposa kupukuta kwa makina abwino koma kumapereka zabwino kwambiri monga kukana dzimbiri komanso kuyeretsa bwino.
Tebulo Loyerekeza Molunjika
| Mbali | Kupukuta kwa Makina | Kupukuta kwamagetsi
|
| Njira | Kupukuta thupi pogwiritsa ntchito zinthu zopyapyala pang'onopang'ono (sandpaper, mawilo opukutira). | Kusungunuka kwa electrochemical mu bafa ya asidi (monga phosphoric/sulfuric acid). |
| Cholinga Chachikulu | Pezani kukongola kwapadera ndi mtengo wotsika wa Ra (kusalala). | Sinthani magwiridwe antchito: kukana dzimbiri, kuchotsa madontho a madzi, kuyeretsa.
|
| Kuchotsa Zinthu | Yosankha, imatha kupopera ndi kuwononga mawonekedwe a pamwamba. | Yofanana, imachotsa zinthu zonse pamalo owonekera, ndipo imakonda nsonga kuposa zigwa.
|
| Umphumphu Wapamwamba | Imatha kusiya tinthu tomwe timayabwa, chitsulo "chogwiritsidwa ntchito", mabala ang'onoang'ono, ndi kupsinjika kwa ma tensile komwe kumatsalira. | Amapanga malo oyera, opanda kuipitsidwa ndi wosanjikiza wa okosijeni (wa chitsulo chosapanga dzimbiri).
|
| Kukana Kudzikundikira | Pakati. Malo osalala amatha kuchepetsa kuukira koyamba, koma zinthu zodetsa zomwe zili mkati ndi wosanjikiza wolakwika zimapangitsa malo oyambira. | Zabwino Kwambiri. Zimachotsa gawo lofooka la pamwamba ndikupanga gawo lolimba, lofanana.
|
| Kuyera ndi Ukhondo | Zabwino. Malo osalala ndi osavuta kuyeretsa, koma ming'alu yaying'ono imatha kukhala ndi mabakiteriya ndi zinthu zodetsa. | Zabwino kwambiri. Zimapanga malo osalala pang'ono, osamata, komanso opanda ming'alu omwe ndi osavuta kuwathira. Ndi abwino kwambiri m'mafakitale opanga mankhwala, chakudya ndi zakumwa, komanso mafakitale a semiconductor. |
| Kutha kwa Jiyometri | Zabwino kwambiri pa ma geometries akunja, osavuta. Zovuta kapena zosatheka panjira zovuta zamkati, mabowo ang'onoang'ono, kapena machubu aatali. | Zabwino kwambiri pa ma geometries akunja, osavuta. Zovuta kapena zosatheka panjira zovuta zamkati, mabowo ang'onoang'ono, kapena machubu aatali. |
| Zotsatira za Ra (Zachizolowezi) | Ikhoza kupeza Ra yotsika kwambiri (< 0.25 µm / 10 µin) ngati itakhala ndi khama lokwanira. | Kawirikawiri zimapangitsa kuti Ra ikhale yokwera kuposa kupopera kwa makina (monga, 0.4-0.8 µm / 16-32 µin), koma imagwira ntchito bwino kwambiri.

Sankhani Kupukuta Kwamakina pamene:
Chofunika kwambiri ndi mawonekedwe okongola komanso mawonekedwe agalasi.
· Mtengo wotsika kwambiri wa Ra ndiye chinthu chofunikira kwambiri chomwe chatchulidwa.
· Gawoli lapangidwa kuchokera ku chinthu chosapanga dzimbiri pomwe gawo lopanda kanthu silili vuto.
· Mtengo ndi chinthu chachikulu chomwe chimapangitsa kuti ntchito yokonza magetsi isakhale yophweka, ndipo ubwino wogwiritsa ntchito magetsi si wofunikira.
Sankhani Electropolishing pamene:
· Kukana dzimbiri ndiye chinthu chofunika kwambiri (monga malo okhala m'madzi, mankhwala, kapena azachipatala).
· Ukhondo wochuluka kwambiri komanso kuyeretsa thupi ndikofunikira (monga mankhwala, bio-processing, zida za chakudya).
· Muyenera kupukuta ma geometri ovuta kapena malo amkati.
· Muyenera kuchotsa gawo lomwe lakhudzidwa ndi ntchito kuti mugwire bwino ntchito (monga, muzinthu zamlengalenga).
· Muyenera kuonetsetsa kuti thupi lanu limatulutsa mpweya woipa komanso kuti thupi lanu likhale ndi moyo wabwino wotopa.
Chifukwa chake, kusankha kumaliza pogwiritsa ntchito mtengo wa Ra kokha ndi cholakwika. Kusankha kuyenera kuyendetsedwa ndi ntchito ya gawolo. Pa chifaniziro chokongoletsera, kupukuta kwa makina ndi kwabwino kwambiri. Pa chinthu chofunikira kwambiri mu pampu ya mtima kapena reactor ya mankhwala, kupukuta kwa magetsi nthawi zambiri kumakhala chisankho chabwino kwambiri chaukadaulo.
